A sleeve for covering vehicle wheels includes a fabric band having an annular arrangement and therefore with a circumferential path as a result of the annular geometry, the band having such proportions and being enabled to cover and surround an external region of a wheel of a vehicle. The fabric band has a central area along its circumferential path and at least one lateral area adjacent to the central area following the same circumferential path. The at least one adjacent lateral area of the band has a surface density value lower than the surface density value of the central area of the same band. The band also presents a textile or fabric continuity in the mutual contact between its central area and at least one adjacent lateral area, the band being formed in one piece or textile body.

Disclosed is a portable escape device for self-rescue in the case of an auto tyre being trapped in a pit, comprising support posts, a clamping device fitted to the support posts, and a jacking device fitted to the clamping device. The support posts are fixedly mounted onto spokes. The clamping device clamps an auto tyre. The jacking device protrudes and extends out of a top face of a tyre portion. The portable escape device for self-rescue in the case of an auto tyre being trapped in a pit can release the trapped auto tyre and perform self-rescue fast and reliably, and is convenient to carry.

What is disclosed is a wheel, typically for use in conjunction with an agricultural irrigation system such as a pivot or wheel line. The wheel has a disc shaped body having a hub to attach to an external frame. The wheel has a plurality of feet attached to the circumference of the body. The feet are generally channel shaped having two ends at either end of the channel. The feet are positioned at the circumference of the body either on the circumference or in indentations or grooves on the circumference such that the ends of the feet overhang the body. Preferably the feet have a space, opening or void between the feet to allow for the passage of snow, mud or other material.

A center pivot irrigation system wheel including a hub having an axis of rotation and having lateral and oppositely lateral sides; a plurality of spoke pairs having distal ends and having proximal ends, each proximal end being attached to the hub, each spoke pair having lateral and oppositely lateral spokes, each lateral spoke being intersected by an axially extending plane of orientation, and said each oppositely lateral spoke being intersected by the same plane of orientation; a first plurality of axially extending through spaces, each through space being bounded by an adjacent pair of the spoke pairs; an annular rim having an outer surface, the distal end of each spoke being fixedly attached to the rim; and a plurality of treads, each tread being fixedly attached to the annular rim's outer surface.

Annular tire overlay (11) for drawing onto the rolling surface of tires (40), which has a tread (17) on its outside and a gripping surface (15) on its inside, which tire overlay (11) is so designed that contact between the rolling surface of the tire (40) and the surfacing of the road is prevented by the tire overlay (11) when the tire overlay has been drawn onto a tire. The said tire overlay (11) is provided with a flange (21) which stops the tire overlay (11) from shifting in the axial direction of the wheel. Advantageously, the tire overlay is additionally stiffened by a flange (21) of planar form to keep the contact area on the surface below small.

Disclosed is a device for diverting water from within a channel of a wheel having a bead ring. The device comprises an adapter having a cylindrical depression, the cylindrical depression comprising a socket for securing the device to a wheel. The device further comprises a diverter arm coupled to the adapter and extending away from the adapter, the diverter arm extending laterally outward and comprising one or more ramps. The adapter may be bolted into a bead ring of the automobile wheel. The one or more ramps may be disposed within a channel of the wheel between the bead ring and the face of the wheel. A side of the diverter arm facing the channel may be curved to allow the ends of the one or more ramps to lie flush against the channel. The one or more ramps may be inclined away from the face of the wheel.
